BOOK MIRROR Filed Oct. 27. 1927 BYjW ATTORNEY Patented May 12, 1931 UNITED STATES PATENT OFFICE SHOJIRO YOSHIOKA, on NEW YORK, N. Y., AssIeNon '10 RINKICHI D01, or SENIDAI, JAPAN BOOK MIRROR Application filed October 27, 1927. Serial No. 229,145.

The main object of this invention is to provide a mirror mounted on the inner surface of the cover of a book which serves as an agent through means of which ones personal L; appearance may be indicated.

Another object of this invention is to provide a mirror which is mounted upon the reverse side of the cover of a book in such manner that it may be readily removed from place for the purposes of replacement or substitution.

The above and other objects will become apparent in the description below, in which characters of reference refer to like-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a perspective View, showing one of the cover members in open position, said cover member having a mirror mounted thereon.

book cover per se, showing the guides and mirror as used.

Figure 3 is a longitudinal sectional elevational View taken on line 33 of Figure 2.

535 Referring in detail to the drawing, the

numeral indicates'the back cover of a book.

This back cover cooperates with a similar front cover 11 between both of which a plurality of pages 12 are bound side by side, The reverse surface 13 of the front cover 11 p of the. book has a pair of guide rails 14 and 15 mounted thereon. These rails each have an inclined tongue 16. These tongues extend upwardly toward each other and form a I triangular space between the-tongues and the surface 13 of the book cover 11. The rails 14 and 15 are securedj'to the front book cover through ribbons or similar other means. The upper ends of the guides are connected by a semi'circular portion 17 which is similar in cross section to that of the rails. Between the guides 14 and '15 near the portion where they join member 17, a recess 18 is formed in the reverse surface 13 of the book coverll.

This recess houses a slightly curved spring 19 which is secured in the recess at one end, and the intermediate portion of said spring finger projects above the-surface 13. The triangular channels 20 formed between the 53 tongues 16 and the surface of the book, re-

Figure 2 is a front elevational view of the ceive the inclined edges of a circular mirror 21 which is adapted to be moved inwardly between the guides and lies seated under the semi-circular element 17. The reverse surface of the mirror 21 has a strip of cloth 22 mounted thereon which extends diametrical- 1y across the mirror and its one end projects therefrom in the form of a grip tab 23, by which means the entire mirror may be extracted from between the guides. The use of the mirror is designed to aid in satisfactorily arranging the personal appearance of one and its uses are obvious. The mirror 21 is removably mounted in the book so that when fracture occurs it may readily be withdrawn from between the guides for I replacement or substitution, and it may also readily be retained in place so that it will not easily dislodge. The resilient finger 19,b v lying above the surface 13 of the book cover 11, engages the surface of the strip 22 and thereby firmly seats the edges of the mirror in the triangular grooves 20. When the mirror is to be extracted the tab 23 is manipulated by the fingers until the mirror 21 is entirely withdrawn from between the guide rails 14 and 15.

triangular groove, a .mirror provided with inclined edges received in said guides and slidable through the open end of said member to a position in said bight portion, arcurved resilient member mounted in a recess of said surface adjacent to said bight portion to engage the under side of said mirror, a strip extending diametrically of said mirror and projecting beyond an edge thereof. v

In testimony whereof I affix my signature.
